POSSIBILITIES FOR CONTROLLING THE CONNECTION BETWEEN WASTEWATER TREATMENT PLANTS AND RECEIVING WATER BODIES

Abstract

With increasing water supply and canalization the quality of the water playing the role of receiver often deteriorates. Among other problems, the not sufficient removal of plant nutrients by the traditional purification technology causes difficulties. Considering that the removal of fertilizers results in a significant increase in the costs of wastewater treatment, it is expedient to keep the extent of removal just at the yet acceptable level of the pollutant. This paper deals with the removal of phosphorus as fertilizer on a transport theoretical basis. As a result, a qualitative connection is established between water quality and water management on the one hand and the operation of the wastewater treatment plant on the other hand.
